Yes, sort of. This is kind of a design decision to be made, and I'll leave
that to DJ: either fix all the sources and Makefiles to use '*.s', or
ensure that the source distribution file names are really '*.S'. My 
last set of changes favours the latter choice.

Not necessarily. As above, we can either change the makefile to clean away
'*.s' (as I did), or change mkstubs.c to actually write *.S files. 

Generally, the current Makefiles do work even for a non case-preserving
source distribution, but some quirks had been overlooked. These can either
be changed locally (using patches like the ones I sent), or globally,
by distributing the sources with the upper-case .S intact.

That'd be the other choice, yes.
